Applicazioni

Protease from Aspergillus saitoi has been used in a study to assess sequence coverage and resolution in hydrogen exchange of large proteins. It has also been used in a study to investigate the conversion of soybean curd isoflavone glycosides to their aglycones through β-glucosidase..

Azioni biochim/fisiol

Protease from Aspergillus saitoi was shown to also function as a β-glucosidase.

Definizione di unità

One unit will hydrolyze hemoglobin to produce color equivalent to 1.0 μmole (181 μg) of tyrosine per min at pH 2.8 at 37 °C (color by Folin-Ciocalteu reagent).

This review covers the unique catalytic and molecular properties of three proteolytic enzymes and a glycosidase from Aspergillus. An aspartic proteinase from A. saitoi, aspergillopepsin I (EC 3.4.23.18), favors hydrophobic amino acids at P1 and P'1 like gastric pepsin. However

A gene encoding the sweet-tasting protein thaumatin (tha) with optimized codon usage was expressed in Aspergillus awamori. Mutants of A. awamori with reduced proteolytic activity were isolated. One of these mutants, named lpr66, contained an insertion of about 200 bp

An Aspergillus saitoi protease preparation, Molsin, was found to contain beta-glucosidase as well as protease activities. Application of Molsin to soybean curd improved its functionality by converting the contained isoflavone glycosides to their aglycones through beta-glucosidase, and also modified the

The broad-spectrum antibacterial activity exhibited by three Pediococcus strains isolated from beer was preliminarily characterized. Factors affecting the production rate of bacterial inhibitors were screened and the effects of simultaneous cultivation of Lactococcus and Pediococcus on the production of inhibitory

The crystal structure of aspergillopepsin I (AP) from Aspergillus phoenicis has been determined at 2.18 A resolution and refined to R and R(free) factors of 21.5 and 26.0%, respectively. AP has the typical two beta-barrel domain structure of aspartic proteinases.
